The int. wipers on my 94 GASE don't work at all, but all other wiper functions are OK. I looked inside the motor cover, but didn't see anything obviously wrong. Any ideas?

Then my thinking is the switch itself, as your rotate it, won't engage the interval function. Or, I believe there is a relay and or fuse that is dedicated for the interval function, however, I think only an owner's manual can point those relays/fuses out for ya, Haynes doesn't, sigh.

Start with trying to see if it the fuse/relay, as if it the switch, that gets involved removal, what with airbag disabling and such.

it could also be the wiper board itself (the motor cover)...working in my dealership, weve had to replace alot of them on trucks (recall), when someone did come in and they describbed what you described it was the wiper board, and there wasnt nothing you could see wrong with it. I would check fuses, relays, switch, then the board. Hope that helps a bit.
